These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.

[0040] In existing technology, a cabinet air conditioner has an air inlet and an air outlet, which are connected by an air duct. A fan assembly is installed within the air duct corresponding to the air inlet, and a heat exchange assembly is installed above the fan assembly. The air outlet is located on the side of the heat exchange assembly away from the fan assembly. Air is drawn from the air inlet by the fan assembly, passes through the air duct and undergoes heat exchange with the heat exchange assembly, and is then blown out through the air outlet. A drip tray is also installed below the heat exchange assembly to collect condensate.

[0041] However, when existing cabinet air conditioners are running, the airflow blown out by the fan assembly gradually becomes turbulent along the air duct, resulting in relatively high noise during airflow.

[0042] To overcome the deficiencies in the prior art, the present application provides a flow guiding structure, a water receiving tray, and an air conditioner. The flow guiding structure includes a flow guiding component, and the flow guiding ribs are connected to the mounting part of the air conditioner so that the flow guiding component is located inside the air duct of the air conditioner, specifically between the fan assembly and the heat exchange assembly of the air conditioner. A rectifier is provided on the flow guiding component, and the rectifier is adapted to the extension direction of the air duct.

[0043] In this way, when the fan assembly is running to discharge air through the air duct to the heat exchange assembly, the airflow in the air duct can pass through the guide component, so that the guide component can guide the airflow and adjust the flow direction of the airflow relative to the heat exchange assembly. Furthermore, when the airflow passes through the guide component, the rectifier on the guide component can further rectify the airflow to reduce the degree of airflow turbulence, making the airflow in the air duct smoother, thereby reducing the noise during airflow.

[0044] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0045] Reference Figures 1 to 3 As shown in the figure, this application provides a flow guiding structure, including:

[0046] The air guide 120 is used to connect with the mounting part of the air conditioner and is installed in the air duct 230 of the air conditioner.

[0047] The guide 120 has a rectifier 130, which is configured to adapt to the extension direction of the air duct 230.

[0048] The air conditioner body 200 contains a fan assembly 210 and a heat exchange assembly 220. The fan assembly 210 is located at the lower part of the air conditioner body 200, with its air inlet on one side and its air outlet at the top, so that the fan assembly 210 blows air upwards. The heat exchange assembly 220 (evaporator) is located at the upper part of the air conditioner body 200. The heat exchange assembly 220 is inclined inside the air conditioner body 200 so that the airflow in the air duct 230 must pass through the heat exchange assembly 220 for heat exchange before it can be blown out of the air outlet on the air conditioner body 200.

[0049] It is understood that the installation part of the air conditioner can be the water tray body 110 or other components or structures within the air duct 230. This application does not limit this. The following description uses the water tray body 110 as the installation part.

[0050] Specifically, the water tray body 110 is connected to the air conditioner body 200. (See reference...) Figure 5 As shown, the lower end of the heat exchange component 220 extends into the water receiving pan body 110. When the heat exchange component 220 exchanges heat with the airflow, condensation will form on its surface. Under the action of gravity, the condensation flows along the heat exchange component 220 into the water receiving pan body 110 to avoid the condensation dripping directly onto other components inside the air conditioner body 200.

[0051] The guide element 120 is connected to the side of the water receiving pan body 110 facing the heat exchange component 220, so that the guide element 120 is located between the heat exchange component 220 and the fan assembly 210. The airflow blown out of the air outlet of the fan assembly 210 can pass through the guide element 120. The guide element 120 guides the flow direction of the airflow so that the airflow passes through the evaporator more stably.

[0052] Furthermore, a rectifier 130 is provided on the air guide 120, and the rectifier 130 is adapted to the air duct 230 structure of the air conditioner body 200. This allows the rectifier 130 to better rectify the airflow flowing through the air guide 120, thereby reducing the degree of airflow turbulence and keeping the airflow smooth. This ensures that the airflow can pass through the heat exchange component 220 smoothly and stably, thereby reducing the noise when the airflow passes through the heat exchange component 220.

[0053] Therefore, the flow guiding structure provided in this application embodiment includes a flow guiding component 120 disposed on the water receiving pan body 110. The water receiving pan body 110 is connected to the air conditioner so that the flow guiding component 120 is located in the air duct 230 of the air conditioner, specifically between the fan assembly 210 and the heat exchange assembly 220 of the air conditioner.

[0054] A rectifier 130 is provided on the guide member 120, and the rectifier 130 is adapted to the extension direction of the air duct 230. In this way, when the fan assembly 210 is running to discharge air through the air duct 230 to the heat exchange assembly 220, the airflow in the air duct 230 can flow through the guide member 120, so that the guide member 120 guides the airflow and adjusts the flow direction of the airflow relative to the heat exchange assembly 220. Furthermore, when the airflow flows through the guide member 120, the rectifier 130 on the guide member 120 can further rectify the airflow to reduce the degree of airflow turbulence, making the airflow in the air duct 230 smoother, thereby reducing the noise during airflow.

[0055] In some embodiments, refer to Figures 3 to 6 As shown, the flow guide 120 includes:

[0056] Support ribs 121, at least two support ribs 121 are provided, and at least two support ribs 121 are spaced apart on the same side of the mounting part;

[0057] At least two guide vanes 122 are provided, and at least two guide vanes 122 are spaced apart on the support rib 121 along the extending direction of the support rib 121.

[0058] The rectifier 130 is mounted on the guide vane 122.

[0059] It is understandable that at least two support ribs 121 are provided, with each support rib 121 spaced apart on the same side of the water receiving tray body 110 along the extension direction of the water receiving tray body 110, so that the support ribs 121 can provide relatively stable support for the guide vanes 122 provided thereon, preventing the guide vanes 122 from shaking or resonating with the airflow.

[0060] For example, in this embodiment, the support rib 121 is a rib plate or rib sheet arranged along a vertical plane. In other embodiments, the support rib 121 may also be a rib rod or rib strip. This application does not limit this.

[0061] Along the extension direction of the support rib 121, at least two guide vanes 122 are arranged sequentially at intervals from the end of the support rib 121 near the water receiving tray body 110 to the end of the support rib 121 away from the water receiving tray body 110, so that the guide vanes 122 can stably guide the airflow.

[0062] Since the guide vane 122 has a larger surface area than the support rib 121, it has a stronger guiding effect on airflow. Therefore, the rectifier 130 is set on the guide vane 122, which allows for more space for the rectifier 130 and facilitates the cooperation between the guide vane 122 and the rectifier 130, thereby improving the rectification effect on airflow, effectively reducing the degree of airflow turbulence, and thus reducing the noise when the airflow passes through the heat exchange component 220.

[0063] In practice, multiple support ribs 121 are spaced apart along the extension direction of the water receiving tray body 110, with consistent spacing between each support rib 121. Similarly, multiple guide vanes 122 are spaced apart along the extension direction of the support ribs 121, with consistent spacing between each guide vane 122. This allows the support ribs 121 and guide vanes 122 to cross-connect, forming multiple rectangular grids of the same size, ensuring a relatively uniform and consistent airflow guidance and rectification effect.

[0064] In some embodiments, refer to Figures 4 to 6 As shown, the guide vane 122 is inclined relative to the heat exchange assembly 220 in the air duct 230.

[0065] It is understandable that setting the guide vane 122 to be tilted relative to the water receiving tray body 110 can make the orientation of the guide vane 122 correspond to the tilt direction of the heat exchange component 220, so that the air flowing through the guide vane 122 can pass through the heat exchange component 220 more smoothly, reducing the resistance between the air and the heat exchange component 220, thereby reducing the noise when the airflow passes through the heat exchange component 220.

[0066] It should be noted that the direction of the flow guide 122 should be tilted toward the heat exchange component 220 so that the flow guide 122 can smoothly guide the airflow passing through the flow guide 122 toward the heat exchange component 220.

[0067] Among them, such as Figure 4 and Figure 5 As shown, the windward side of the guide vane 122 is the lower side of the guide vane 122 in the figure, and the windward side is located on the side of the guide vane 122 facing the water receiving tray body 110 and the evaporator assembly, while the leeward side of the guide vane 122 is the upper side of the guide vane 122 in the figure, which is located on the side of the guide vane 122 away from the water receiving tray and the evaporator assembly. The guide vane 122 mainly guides the flow direction of the airflow through the windward side.

[0068] Among them, reference Figures 4 to 6 As shown, the tilt angle of the guide vane 122 is greater than or equal to 12° and less than or equal to 15°.

[0069] It is understood that the tilt angle of the guide vane 122 is set in the range of 12° to 15°. For example, the tilt angle can be set to 12°, 13°, 14° or 15°, and this application does not limit this. This setting can both ensure the guiding effect of the guide vane 122 on the airflow and reduce the friction between the guide vane 122 and the airflow.

[0070] If the tilt angle of the guide vane 122 is too small, it will be difficult for the airflow to pass smoothly through the heat exchange component 220 under the guidance of the guide vane 122, resulting in a large noise when the airflow passes through the heat exchange component 220.

[0071] If the tilt angle of the guide vane 122 is too large, the windward side of the guide vane 122 will easily block the airflow, resulting in greater airflow noise and greater airflow resistance, thus affecting the airflow volume.

[0072] Furthermore, refer to Figures 4 to 6 As shown, the rectifier 130 is located on the side of the guide vane 122 facing the heat exchange assembly 220.

[0073] It is understandable that since the guide vane 122 guides the airflow direction through the windward side, placing the rectifier 130 on the windward side of the guide vane 122 can improve the efficiency of the rectifier 130. The combination of the rectifier 130 and the guide vane 122 helps the rectifier 130 to more fully and effectively sift the airflow on the windward side of the guide vane 122.

[0074] In specific implementation, a rectifier 130 can also be provided on the leeward side of the guide vane 122 to further improve the rectification effect of the rectifier 130. This application does not limit this.

[0075] In some embodiments, refer to Figure 3 , Figure 4 and Figure 6 As shown, the rectifier 130 consists of a plurality of protrusions arranged sequentially along the extension direction of the guide vane 122, and the extension direction of each protrusion is consistent with the extension direction of the air duct 230.

[0076] It is understandable that the guide vane 122 extends horizontally, and the rectifier 130 is set to extend in a direction perpendicular to the direction of the guide vane 122. This allows the rectifier 130 to extend relatively vertically, so that the rectifier 130 is adapted to the extension direction of the air duct 230, which facilitates the rectifier 130 in rectifying the upward airflow.

[0077] The rectifier 130 extends in a direction that corresponds to the airflow direction, so as to minimize the resistance of the rectifier 130 to the airflow while rectifying the airflow, reduce the energy loss of the airflow, and ensure the air volume and speed of the air conditioner.

[0078] By making the rectifier 130 a protrusion, the airflow can pass through the rectifier 130 under the guidance of the guide vane 122, so that the rectifier 130 can organize the scattered airflow and reduce the turbulence and cyclone of the airflow.

[0079] Furthermore, refer to Figure 6 As shown, the tops of each protrusion are pointed, rounded, or flat.

[0080] Specifically, in this embodiment, the top of the protrusion is flat-angled so that each protrusion forms a tooth-like structure. While rectifying the airflow, it can effectively ensure the structural stability of the guide vane 122 and prevent the guide vane 122 from shaking, deforming or resonating under the influence of airflow.

[0081] In other embodiments, the top of the protrusions may be set to a sharp angle so that the protrusions form a sawtooth-like structure, so that the rectifier 130 can generate a more effective rectification effect on the airflow. Alternatively, the top of the protrusions may be set to a rounded corner so that the protrusions form a wave-like tooth structure, so that the rectifier 130 is smoother, reducing friction with the airflow, thereby reducing the energy loss of the airflow and reducing airflow noise. This application does not limit this.

[0082] In addition, such as Figures 4 to 6 As shown, in some embodiments, the guide vane 122 is arc-shaped, with the concave side of the arc facing the heat exchange assembly 220.

[0083] It is understandable that setting the guide vane 122 to an arc shape can make the angle of the guide vane 122 tilt more smoothly, so that the guide vane 122 can guide the airflow and adjust the flow direction more smoothly.

[0084] For example, in this embodiment, the guide vane 122 along Figures 4 to 6 As shown, its cross-section along the vertical direction is arc-shaped.

[0085] In other embodiments, the cross-section of the guide vane 122 along the horizontal direction can be set to be arc-shaped so that the guide member 120 forms a fan-shaped structure, further expanding the effective area of ​​the guide member 120 and improving the airflow guiding effect of the guide member 120.

[0086] Furthermore, the thickness of the guide vane 122 in the middle along its own extension direction is greater than the thickness on both sides.

[0087] It is understandable that this configuration allows the cross-section of the guide vane 122 in the vertical direction to be further streamlined, thereby reducing the resistance of the airflow passing through the guide vane 122, reducing the energy loss of the airflow, and ensuring that the airflow passes through the heat exchange component 220 more efficiently.

[0088] This application also provides a water receiving tray 100, including a water receiving tray body 110 and a flow guiding structure from any of the above embodiments disposed on the water receiving tray body 110.

[0089] This application also provides an air conditioner, including an air conditioner body 200 and a flow guiding structure as described in any of the above embodiments disposed on the air conditioner body 200, or a water receiving tray 100 disposed on the air conditioner body 200.

[0090] The water receiving tray and air conditioner provided in this application embodiment are configured with a water receiving tray 100, which includes a water receiving tray body 110 and a guide member 120 disposed on the water receiving tray body 110. The water receiving tray body 110 is connected to the air conditioner, such that the guide member 120 is located within the air duct 230 of the air conditioner, specifically between the fan assembly 210 and the heat exchange assembly 220 of the air conditioner. A rectifier 130 is provided on the guide member 120, and the rectifier 130 is adapted to the extension direction of the air duct 230.

[0091] When the fan assembly 210 is running and exhausts air through the air duct 230 to the heat exchange assembly 220, the airflow in the air duct 230 can pass through the guide member 120, so that the guide member 120 guides the airflow and adjusts the flow direction of the airflow relative to the heat exchange assembly 220. Furthermore, when the airflow passes through the guide member 120, the rectifier 130 on the guide member 120 can further rectify the airflow to reduce the degree of airflow turbulence, making the airflow in the air duct 230 smoother, thereby reducing the noise during airflow.
